Column names could stick to the top of screen when scrolling down report tables

It would be awesome that, when scrolling down and the header row with Column names is not visible, that instead this row would stick at the top of the screen and provide an always clear view of the data being shown.

Even Piwik team members don't know about the order of columns it is hard to remember in all views... This would improve UX for All users at once!
